...Has apparently stagnated in Pennsylvania in the last few weeks, according to a Quinnipiac University Poll out today. The Illinois senator and Democratic presidential candidate grabbed 17 percent of the prospective vote in the new poll, taken from March 19-25, compared with 18 percent in a poll at the beginning of March. Sen. Hillary Clinton, meanwhile, bounced back to 36 percent from 29 percent in the earlier poll. The early March poll suggested that Obama was making significant headway against Clinton in the Keystone State, having narrowed a 26-point margin to 9 points between early February and early March. Former Sen. John Edwards dropped to 9 points, after grabbing 11 percent in the last two polls.

On the Republican side, former New York mayor Rudy Giuliani continues to lead, although by significantly less than earlier in the month. He grabbed 33 percent of the prospective vote. Sen. John McCain got 18 percent. The difference appeared to come mostly from the possible addition of former Sen. Fred Thompson to the race. Thompson, who is reportedly considering a run, was favored by 6 percent. He was not considered in previous polls. Former Gov. Mitt Romney got 5 percent.

Things continue to look good for Giuliani in head-to-head matchups with Democrats. The poll has him beating the three Democratic frontrunners, Clinton, Obama and Edwards. That said, his 11-point lead over Clinton in early March shrank to 4 points in this poll.

Also interesting is a finding in the poll that only 42 percent of Pennsylvanians support moving up the late April primary to early February (28 percent oppose, 30 percent don't know).
